Stream management

Zulip User Documentation

Zulip is a group chat app. Its most distinctive characteristic is that
conversation within an organization is divided into “streams”
and further subdivided into “topics”, so that
much finer-grained conversations are possible than with IRC or other
chat tools.

Most people use Zulip on the Web. There are also mobile apps for
Android/iOS, and desktop apps for Mac/Linux/Windows, which can be
downloaded here.

One Zulip account, associated with a particular company, project, or team,
is known as an organization.
